Task 1: If we want to find out information on the internet, what websites might we use to find it? Generate a list. Check at the bottom of the page - did you manage to find any that are in the Top 5 search engines in the world?

 

We use search engines to find information. 

 

Let’s say I am looking for information on scratch programming. What could I type into google? Type 'scratch' into google - the number of results at the top is how many the algorithm (code) that google uses has found. What do you think the other search engines will find? Try this with bing, ask and baidu (www.baidu.com in Chinese but it does find results).

 

They all find different numbers of results because they are searching in different ways. Repeat this exercise with different words:

– Chocolate 

- Chocolate factory

- Cocoa beans.

 

Task 2: Write a short explanation in books as to why the results are different (use the word algorithm).

 

We need to ensure our searches are safe and that we type in searches that will give us what we want to see. The more accurate the search, the more likely you will get the right result.

 

Search the word “scratch” again. Go down the list of results. Are they all scratch programming websites? Why not?

 

Scratch can have different meanings so we need to be more accurate. What could we add to our search? Scratch programming. How many results do we get now? 

 

Main task: Complete the Twinkl search engine sheet below. 

 

Extension:

 

Think back to our lessons about being cyberwise. How can accurate searches keep us safe on the internet?
